In all uses of VIR_DIR_CLOSE() except one, the DIR* is never referenced after closing all the way until it goes out of scope. virCapabilitiesInitCaches(), however, reuses the same DIR* over and over in a loop, but due to having many error conditions that result in a goto out of the loop, it's not well suited to reducing the scope of the variable until we introduce a g_autoptr cleanup function for DIR*. In preparation for doing just that, we need to get rid of the side effect of VIR_DIR_CLOSE() setting the DIR* to NULL, so in this one case, let's manually set the DIR* to NULL. Then in an upcoming patch we can safely remove the side effect from VIR_DIR_CLOSE(). This extra/ugly bit of code is only temporary: once we introduce the g_autoptr cleanup function for DIR*, we will remove this manual close/clear completely anyway.

Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
